Title IMMOBILIZED LEWIS ACID CATALYSTS COATED WITH IONIC LIQUIDS AND USE THEREOF
Abstract

The invention provides a novel immobilized Lewis acid catalyst which exhibits high catalytic activity in an aqueous solution and which permits recovery and reuse or long-term continuous use. The invention relates to an immobilized Lewis acid catalyst comprising a solid substance and a Lewis acid supported on the surface of the solid substance by chemical bonding, wherein the surface of the solid substance and the peripheries of the Lewis acid are coated with an ionic liquid, more specifically, an immobilized Lewis acid catalyst comprising a solid substance such as silica gel or an organic polymer and a Lewis acid stable even in water which is supported on the surface of the solid substance by chemical bonding, wherein the surface of the solid substance and the peripheries of the Lewis acid are completely or partially coated with a hydrophobic ionic liquid

a process for the production of the catalyst

use thereof

and a process for the preparation of compounds with the catalyst.
